Does Smugmug offer a client access/passcode page?

I was an avid Smugmug user for many years before I made the switch to Zenfolio a couple of months ago. Asides for the cleaner look at the time and price, the main reason why I made the switch was because of the ability to create a passcode access page for clients.
I was wondering if smugmug offers a similar feature or have plans to add this feature?


The one feature that I love with smugmug that seems to be missing from Zenfolio is the ability to seamlessly sync my clients favorite images with Lightroom. I loved the ability to have my clients favorites just pop up in my Lightroom library without having to import a Image List every time my client makes any adjustments like I currently have to do with Zen. This feature on Smugmug also allowed me to access my clients favorites immediately on my mobile devices with their app.
Does Zen offer a similar feature? If so, how do I set it up?

If smugmug offers or plans on offering a similar feature, I will make the switch back in a heartbeat.

Here are a couple of links that explains what I am talking about in more detail.
